“Is the unit completely silent during normal operation, no running fans? And will only beep during a power outage? Thank you”

• Runs completely silent. No running fan noises, because there isn't a fan in this model. Beeps during power outages/brown-outs, old battery warnings, and all other errors. Just like the spec-sheet and the free-and-easily-downloadable manual say.

• Thank you for your inquiry. The BN1080G does have a fan, which you may here turn on when the unit is charging the battery or if it needs to adjust to any change in the environment. You will hear a soft hum when the fan is charging, so we could not say the unit is completely silent at all time.
